error occurs during the exception processing sequence for a reset, a double bus fault is gen-
erated. The processor halts and signals the double bus fault status on the processor status
outputs ([PST4–PST0] = $1C). Execution of the reset instruction does not cause a reset
exception, nor does it affect any internal registers except the PC. The execution of this
